Answer to Problem 6RE
Slope
Explanation of Solution
Given:
Calculation:
The slope intercept form of a line is
Where the slope of the line is m ,
And y intercept is b .
Compare the function
Slope
Conclusion:
Therefore, the slope
(b)
To find: the average rate of change of each function.
(b)

Answer to Problem 6RE
The average rate of change is 0
Explanation of Solution
Calculation:
For calculating average rate of change of the function
Let
So second point in
Now as rate of change
Here
So rate of change
Conclusion:
The average rate of change is 0
(c)
To graph: the given function
(c)
